Outdoors, I have zero restrictions.
Indoors, I'm OK with small (<= 4 people) gatherings unmasked as long as nobody has been recently exposed.
I can do indoor spaces with more people if we're all masked and I keep the time short (eg for shopping), but I don't like it much.
For social gatherings this means that "outdoor pubs" and "in someone's flat, with the windows open" are in play, but "indoor pubs" are outside my risk tolerance. Similarly group hikes / runs / sports are fine, but indoor events of any sort are out.
I don't consider that the government guidelines at any given moment provide a sensible approach to risk, and don't factor them into my personal policy.
